I’am trying to have a Hubspot trigger, followed the documentation tutorial for the credentials and scopes. And still have the error message
I followed all the steps, and add the scopes correctly. Even tried with a youtube video ahah.
It begins to make me crazy …
Authorization failed because there is a mismatch between the scopes in the install URL and the app's configured scopes. Please contact the app developer.
Also one interesting comment which i saw also on another site
HubSpot old accounts
Some HubSpot accounts don't have access to all the scopes. HubSpot is migrating accounts gradually. If you can't find all the scopes in your current HubSpot developer account, try creating a fresh developer account.
I guess you have tried to delete everything and start fresh.
